Some buggy video players are broken when the browser doesn't autoplay "autoplay" video because the player's play/pause state doesn't match the browser's. Firefox developers are looking at workarounds like telling the player the video is playing, but not downloading the video.
You can set about:config pref "media.autoplay.enabled" = false to test. YouTube used to be broken. I don't know if it still is.
- throwanem 9y agoI think it still is - I had to re-enable autoplay to get YouTube playlists working properly again. I still have "don't autoplay until tab focused" enabled, though - it isn't a problem there.
- cpeterso 9y agoI'm not sure why "don't autoplay until tab focused" works but "don't autoplay on current tab" does not. btw, I use the "YouTube High Definition" Firefox extension, which allows you to prevent autoplay and tweak other YouTube parameters such as disabling overlay messages and forcing a default video size: https://addons.mozilla.org/en-US/firefox/addon/youtube-high-definition/ https://addons.mozilla.org/en-US/firefox/addon/youtube-high-...
- throwanem 9y agoI suspect it's because the transition between one playlist video and the next triggers the autoplay-prevention code path. "Don't autoplay until focused" wouldn't, because if the tab hasn't been focused then the video's not playing at all, and if the tab has been focused, then autoplay is (I think) permitted without further restriction.
